First Line of Defense
Michal Wallace: Im sitting here watching sendmail process a mail queue on one of my machines. There’s 846 messages in the queue. It’s on number 5, and it’s taken about 10 minutes so far for just this one message: it’s just sitting there waiting to connect to a server that’s very obviously not answering. Every couple minutes or so it tries another mail server for the same domain.
That machine would happen to be the one that I’m on. I certainly don’t envy Michal’s job. One of the recent issues was that he had to deal with was that some spammer decided to generate messages that purported to be from feedvalidator.org addresses, and the bounce messages alone that this caused were enough to gum up the works.
That’s why I have a lifetime account at cornerhost.
